Detailed Description
The QFileOpenEvent class provides an event that will be sent when there is a request to open a file or a URL.
File open events will be sent to the QApplication::instance() when the operating system requests that a file or URL should be opened. This is a high-level event that can be caused by different user actions depending on the user's desktop environment; for example, double clicking on an file icon in the Finder on Mac OS X.
This event is only used to notify the application of a request. It may be safely ignored.
Note: This class is currently supported for Mac OS X only.
